Posted by Nancy Sunshine on 03:32pm Nov 7, 2004 CDT
EXPLANATION! I am an apple cert technician and perform repairs at school. (Not that may mean much) but after examination of the entire midplane and removing and unplugging each component of the board if you have:
1: A buzzing soung in the lower area of your machine you need a new power supply unit. this can also be confirmed by playing with you contrast keys.
2. If you have a whistle/hum/drone that will pick up and slow down with the processor you have a bad fan. A component in the fan and duct (Upper left near optical drive usually) mixes allowing you to hear all the adjustment of the fan speed through a whine. This though would be heard at the top of the machine and can be diagnosed by placing your arm over the heat exhaust vent and seeing if the issue ceases. If so, order a midplane.
3. If you have a high frequency screech from the upper left extemity of the machine, your harddrive is screaming. Replace it
This is a 95 percent accurate diagnosis.You may have a different situation. Dont kill me i have just spent some hours looking over a 17 and 20 inch and am sharing my report.

All in all, The imac SHOULD NOT Make ANY NOISE Except for the white noise of the fan (JUST WIND) Any buzz,drill,whine,grumble, is not normal and needs to be replaced with parts that i believe apple is sending with the next batches of imac G5's. Keep in mind. The regular Tech agents follow a protocal and look up what to do iwhen you call with a problem. Ask for a produc specialist and take some control. Besides they send you to one anyway. Dont take crap either you spent alot for theese they arent just pcs for 600 bucks. Call customer relations if anything else arises.
